ELLIS S. HEL'WITZ, OF BROOKLYN, NEW YORK.

SHOE-HEEL.

Specification of Letters Patent.

Patented Apr. 2, 1918.

Application filed December 8, 1916; Serial No. 135,729.

To all whom it may concern:

Be it known that I, ELLIS S. Hnnwrrz, a subject of KingGeorge V of Great Britain and Ireland, and a resident of the borough of Brooklyn, city andState ofNew York, have invented certain new andv useful Improvements in Shoe-Heels, of which the following is a description in such full, clear, and exact terms as ,will enable any person skilled in the art to which it pertains to make and use the same. I

My invention relates to a rubber heel laced upon the heel of leather shoes to so n the tread of the vwearer. It is especially though not necessarily adapted to use in connection with what are known as French heels on womens shoes. Its principles, however, may be adapted to heels of other makes including the Cuban heel, so called, and the ordinary heel of mens shoes.

The objectof the invention is to insure that the rubber heel be securely fastened to the leather heel and yet be easily attached and detached so that it maybe used in connection with one or more different pairs of shoes and so that it may be purchased by the user and applied without the aid of a shoemaker.

Reference is now had to the accompanying7 drawing in whichigure 1 is a vertical section of the heel pad of the shape adapted approximately for what is known as a French heel and showin the same in place on the heel, and

Fig. 2 is a bottom plan view of the heel.

To this end the heel pad proper, a, c'. e. the part that lies directly under the heel and bears the pressure of the wearer, is formed with an upwardl extending elastic wall 6 which isadapte to' inclose or reoeive the lower part of the heel or indeed the whole of the side walls of the heel if so desired. This depends'entirely upon the selected. height of the wall b. The pad proper a may be formed of rubber with any desired degree of elasticity and the wall, I), being much less in thickness than the pad should be made elastic so that it contracts upon the heel and tends to hold the pad in. a

place thereon.

To assist the elasticity ofthe rubber and increase the durability and strength of the device I cause a sheet metal cup p to .be embedded within the. rubber during the ,vulcanizing process. This cup is preferably formed of drawn sheet metal in the requisite shape and has orifices c stamped or otherwise formed therein so that the rubber enters the orifices and the sheet metal cup does not form too great a separation of the rubber which would impair the durability of the device. This cup, 0, it will be noted from Fig. 1, extends through the interior of the pad a and throughout the area thereof and its walls rise to and into the resilient wall I) of the pad. The cap being of sheet metal such for instance as sheet steel, is resilient and serves to reinforce the elastic gripping effect of the wall 6 against the side of 'the heel.

The device may be readily snapped on and off the heel and will fit the same very snugly and cannot be removed except by positive pulling pressure away from the sole of the For further security I prefer to form the depression, 03, on the top or inner surface of the pad 0, which will operate in the nature of a suction cup forming a sort of partial vacuum tending to hold the pad a, snugly against the bottom surface of the heel. And I also prefer to form on the under surface of the ad a a number of similar depressions e whic form minute suction cups and tend to hold the heel from slipping on a smooth surface, such for instance, as an icy sidewalk.

In connection with my invention it will be noted that its advantage lies in the fact that the device does not have to be handled by the shoemaker as certain other rubber heels long in use have been necessarily handled and are'now handled. Any merchant may carry these devices in stock and dispose of them at will according to his .methods of trade to the ultimate consumer who simply has to snap them on and ofi' the heel as one puts on or removes the welllmown rubber shoe.

' The heel may be easil interchanged from one shoe to another an thus made to wear evenly.

What-I claim is a A detachable rubber heel for shoes comprising a base part or heel pad proper and an upwardly extending elastic wall, the base part adapted to lie under the heel and the wall to extend up and surround the sides of the heel and a resilient metal cup molded in Q momma inward around all sides of the heel to hold the pad in place.

In testimony whereof I have hereuz to signed my name in the presence oftwo wltnesses.
